RE: Axis linking problems (again)



Johan,

Your suggestion doesn't help:

comio.o(.text+0x92): undefined reference to `_tcgetattr__FiP7termios'
comio.o(.text+0x24e): undefined reference to `_tcflush__Fii'
comio.o(.text+0x25c): undefined reference to `_tcsetattr__FiiP7termios'
comio.o(.text+0x332): undefined reference to `_tcsetattr__FiiP7termios'
comio.o(.text+0x494): undefined reference to `_tcdrain__Fi'
comio.o(.text+0x4c8): undefined reference to `_tcdrain__Fi'
comio.o(.text+0x504): undefined reference to `_tcdrain__Fi'
comio.o(.text+0x62a): undefined reference to `_tcflush__Fii'
comio.o(.text+0x650): undefined reference to `_tcsendbreak__Fii'
/projects/12150/axis/eroot/lib/libucc.a(itoa.o)(.text+0x24): undefined
reference
 to `___Mod'
make: *** [main] Error 1   

BR,
Timo
